Mike's assessment is correct. Full qualification is sucessfull completion of Motorola's extensive internal certification process which includes the items Mike indicated as well as criteria such as life cycle testing, producability under all extremes of processing parameters, etc. prior to marking a part as "MC" status. In many instances the "XC" version that enters the "MC" certification process is the same mask set that eventually is used to produce full "MC" devices. Each "XC" version of a device that is produced has an errata sheet indicating all known anomolies (if any). This errata is available on request from any Motorola Semiconductor Field Sales Office. The availability of XC status devices (especially in volume) may vary from device to device and from mask set to mask set. The decision on the appropriate use of "XC" devices should be discussed at length with with your Motorola representative. -- ---- Art Parmet @ Motorola Semiconductor, Marlboro, Ma.
